Brad King 86578eccf2 Simplify CMake per-source license notices
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

Run clang-tidy's modernize-use-override checker.  This checker must have
issues in version 3.8.  It has way too little matches.  And it adds
override to destructors.  Revert the changes on the destructors and
change override to CM_OVERRIDE.

Brad King 0ac18d40c8 Remove `//------...` horizontal separator comments
Modern editors provide plenty of ways to visually separate functions.
Drop the explicit comments that previously served this purpose.
Use the following command to automate the change:

    $ git ls-files -z -- \
        "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |
      egrep -z -v "^Source/cmCommandArgumentLexer\." |
      egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmDependsJavaLexer\." |
      egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmExprLexer\." |
      egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmFortranLexer\." |
      egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmListFileLexer\." |
      egrep -z -v "^Source/cm_sha2" |
      egrep -z -v "^Source/(kwsys|CursesDialog/form)/" |
      egrep -z -v "^Utilities/(KW|cm).*/" |
      xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'

This avoids modifying third-party sources and generated sources.

Brad King 7b6ffa59b1 Source: Sort includes of sys/types.h as clang-format would
When this header is included in blocks where order does not matter, just
place it in lexicographic order as clang-format would by default.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

Commit the result temporarily.  Start a new branch and cherry-pick the
second commit.  Manually resolve conflicts to preserve indentation of
re-ordered includes.  This cleans up the include ordering without
changing any other style.

Use the following command to run `clang-format`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.

Ben Boeckel 06b310b5d5 cmCTestGIT: add an option to initialize submodules on update
Currently, CTest will not initialize any submodules within the already
checked out source tree. Add an option to do so. The use case for not
doing so is that some submodules may not be necessary for the current
test and keeping network usage down may be important.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King 732af7fbba CTest: Do not fail with submodules and Git < 1.6.5.0
Several major Linux distributions still do not provide Git >= 1.6.5.0 in
their stable package lists.  Prior to commit 1173cc4a (Update Git
submodules with --recursive, 2011-02-22) CTest was able to use older Git
versions but simply silently failed to update submodules recursively.
Instead of failing with older Git versions preserve the status quo and
add a warning in the update log.  Users testing projects with recursive
submodules may simply update to a Git new enough to support them.

Brad King a7319cf1c1 ctest_update: Run 'git submodule' at top level
The git submodule porcelain must be executed from the top level of the
work tree.  Use 'git rev-parse --show-cdup' to find the top level
relative to the source tree.  This is better than searching up the tree
for .git ourselves because it will always work the same way Git does and
thus honors settings like GIT_DISCOVERY_ACROSS_FILESYSTEM.

Brad King 7bf8dc1ac9 ctest_update: Support ".git file" work trees
Commit c3781efb (Support Git upstream branch rewrites, 2010-06-08)
assumed that ".git/FETCH_HEAD" exists inside the source tree.  Fix the
implementation to handle a work tree using a ".git file" to link to its
repository.  Use "git rev-parse --git-dir" to locate the real .git dir.

Brad King bbfe241c6a CTest: Parse empty Git commits correctly
Git's diff-tree format has no '\n'-terminated blank line at the end of
its commit message body block if there are no diff lines.  Instead the
message body is terminated by '\0' and there is no diff section.  Teach
CTest to parse the format in this case.

Brad King c3781efb28 ctest_update: Support Git upstream branch rewrites
Use 'git fetch' followed by 'git reset' to update the source tree.  This
is better than 'git pull' because it can handle a rewritten upstream
branch and does not leave local modifications.  After fetch, parse
FETCH_HEAD to find the merge head that 'git pull' would choose to track
the upstream branch.  Then reset to the selected head.

In the normal fast-forward case the behavior remains unchanged.
However, now local modifications and commits will be erased, and
upstream rewrites are handled smoothly.  This ensures that the upstream
branch is tested as expected.

Brad King 67277bacca Teach ctest_update about Git submodules
Git does not automatically checkout the matching version of a submodule
when it checks out a new version of the parent project in the work tree.
If the submodule reference changed in the parent project then we were
reporting the submodule path as a local modification.  Work around the
problem in ctest_update using "git submodule update" after "git pull".
For projects with no submodules this is a no-op.  See issue #10662.
Also add a submodule to the test project for CTest.UpdateGIT to test the
work-around.

Brad King 8bd231866a cmCTestGIT: Refresh index for local modifications
We use 'git diff-index' to detect local modifications after pull.  On
some filesystems the work tree timestamps of a few files may be dated
after the index, making them appear as locally modified.  We address the
problem by using 'git update-index --refresh' to refresh the index and
avoid false local modifications.
